Regardless of what changes you need to make in life to become an overall healthier person, make sure it's for you! Don't be afraid of changes that can make your life better. When you are faced with a challenge, don't give up when it becomes difficult or you don't succeed the first time; get back up and keep going forward. In life we will eventually make a choice we will regret, but the important thing is to not dwell on it. Learn from your choice and move on. It's natural, especially when something isn't going right, we want to try to find out why; but, there are times when there is no explanation and the best thing to do is accept reality and keep an open and positive mind.
